Gaskets & Sealer
So what's the scoop on installing gaskets with sealer? I'm talking about water pumps, oil pans, timing gear covers, things like that not heads.
I have seen reference to using gasket adhesive for some of those components versus a sealer, but others say don't use anything. In high school shop class we used to goop everything with that sticky brown/black permatex, but I'm sure we were doing about everything wrong then.
I'm R&R'ing an engine right now and would appreciate any advice.
Thanks.

I use a gasket adhesive when there is a chance that the gasket will move as I install the part.
Usually it is not necessary to use a sealer if the mating surfaces are perfect and clean and the bolts are torqued. Otherwise (most times) use a sealer. The new siliconized sealers are great and they stand up to high temperature.

I use RTV (silicone sealer) on just about everything. For water pumps, hoses, I use the blue stuff. For hotter temp stuff, like valve cover gaskets, intake gaskets, even a freeze plug, I use the red stuff. I've also used the black stuff on a freeze plug and other misc gaskets before.
I've never had a leak. Ever.
Just my two cents.

I just put a 302 into my truck. I used emblem adhesive on every cork gasket. they will not leak! The thing about emblem adhesive is that its thin, not like permatex. I use the yellow kind. I work at a Ford dealership and our diesel rebuilder uses it (thats why I tried it) and he says the only drawback is that it is hard to pry off the oil pan or whatever you stuck on, because it works like glue.
On my engine it works great.
Hope this helps

just be careful, if your a person who uses silicon especially on the newer cars and trucks, make sure you use the right silicone sealer! these newer engines have all these sensors on them, and using some of these sealers have properties in them that can burn out oxygen sensors and other things like that. so be careful or you might be buying a brand new sensor that costs an arm and a leg...
